Using numerical results for the Blasius exact solution for laminar boundary-layer flow on a flat plate, plot the dimensionless velocity profile, \(u / U\) (on the abscissa), versus dimensionless distance from the surface, \(y / \delta\) (on the ordinate). Compare with the approximate parabolic velocity profile of Problem 9.8.
